Schaeffler Grease sensor

The grease sensor has a diameter of 5 mm and is inserted in a hole in the housing as close as possible to the rolling bearing. The sensor is positioned in the lubricant. This grease sensor optically measures the water content, turbidity, thermal and mechanical wear and the grease temperature directly in the bearing arrangement. This information is transferred by cable to the evaluation unit. The evaluation unit generates an analogue signal that gives the user information rapidly and easily on the condition of the grease.

In the past, bearings were regreased as a function of time. The grease quantities and lubrication intervals were calculated numerically. If the grease sensor is used, regreasing can be carriout out as a function of condition.

The grease sensor facilitates:

• lubrication appropriate to needs
• lower lubricant costs
• prevention of unplanned downtime
• lower maintenance costs
• lower equipment costs.
